I have a 2001 Honda CR-V 5-Speed with 252k miles on it. The vehicle will not come out of reverse once you go in it unless you turn off the car push in the clutch and are able to roll forward then you can feel reverse let go. It will not down shift into 2nd and when you are shifting into 5th gear you can feel it is a little sticky. Anything i could possibly try to do before taking it to the shop? Also where is the transmission fill cap at?
